Chapter 2
Verification Tests
Introduction
This chapter describes the verification tests for the E1343A, E1344A,
E1345A, E1347A, E1355A, E1356A Relay Multiplexers. The three levels
of test procedures described in this chapter are used to verify that the
modules:
• are functional (Functional Verification Test)
• meet selected testable specifications (Operation
Verification)
• meet all testable specifications (Performance Verification)
Test Conditions &
Procedures
See Table 1-1 for test equipment requirements. You should complete the
Performance Verification tests at least once a year. For heavy use or severe
operating environments, perform the tests more often. The verification tests
assume that the person performing the tests understands how to operate the
mainframe, the multiplexers, and the specified test equipment. The test
procedures do not specify equipment settings for test equipment except in
general terms. It is assumed that a qualified, service-trained technician will
select and connect the cables, adapters, and probes required for the test.
Performance Test
Record
The results of each Performance Verification test may be recorded in
Table 2-2, "Performance Test Record," at the end of this chapter. You
may photocopy this form, if desired.
Verification Test
Examples
Each verification test procedure includes an example program that performs
the test. All example programs assume the following configuration:
• HP 9000 Series 200/300 computer
• HP BASIC programming language
• Multiplexer address 70914
• Multiplexer card number 1
• 3458A Digital Multimeter (DMM)
